Anthems Of Rebellion is the only Arch Enemy album to feature clean vocals. The clean vocals were sung by Christopher Amott on "End of the Line" and "Dehumanization".

In 2006, Michael Amott made his voice acting debut when he appeared on the Adult Swim show Metalocalypse. In the episode "Snakes 'n Barrels", he voiced scientist Dr. Amomolith Chesterfield and Snakes 'n Barrels bassist Antonio Tony DiMarco Thunderbottom, who would end up getting his memory erased during the first song of their reunion show.

Michael Amott is a vegetarian. He is also a self taught guitar player.

On their first album Black Earth, all the songwriting was done by Michael Amott, and he even played bass guitar, contrary to the album's liner notes, which listed vocalist Johan Liiva as handling bass duties. Amott later revealed that he had the credits listed that way to make the album seem like more of a "band" effort.

Angela Gossow is a vegan.

Before she left the band in 2014 Angela Gossow was the only bandmember who is from Germany; the others are from Sweden. But after the replacements of Angela and Nick Cordle joined the band this wasn't the case anymore. Alissa White-Gluz is born in Canada and Jeff Loomis in Appleton, Wisconsin.
